Description

Technical Field

[0001] The utility model relates to the technical field of road detection, in particular to a road surface flatness detection device. Background Technique

[0002] The road surface flatness refers to the deviation value of the longitudinal unevenness of the road surface. Road surface flatness is an important index in road evaluation and road construction acceptance, mainly reflecting the flatness of the longitudinal section profile curve of the road surface. When the longitudinal section profile curve of the road surface is relatively smooth, it means that the road surface is relatively flat, or the flatness is relatively good, otherwise it means that the flatness is relatively poor. A good road surface requires good flatness. Road surface flatness detection devices are usually used to evaluate the flatness of the road surface to ensure the safety and comfort of the road. The highway continuous eight-wheel flatness meter is mainly used for detecting road surface flatness; it has the functions of continuous measurement, automatic operation, high measurement accuracy, high speed, and displaying and printing the standard deviation of road surface flatness. This kind of road surface flatness detection device is usually used for various types of road surfaces such as highways, expressways, and airport runways to evaluate their flatness and safety and guide road maintenance and repair work.

[0003] When the existing road surface flatness detection device is actually used, it is not convenient to clamp and fix detectors with different widths and buffer and shock absorption.

[0004] After retrieval of existing patents: A road surface flatness detection device (publication number: CN208121528U), including a vehicle body, a plurality of rollers are uniformly installed on the lower side of the vehicle body, and a plurality of clamping mechanisms for fixing the rollers are arranged at the lower end of the vehicle body. The clamping mechanism includes a fixing block rotatably connected to the vehicle body through a thrust ball bearing. A limiting block is fixedly arranged on the central axis of the roller. A clamping groove for matching the clamping block is arranged at the upper end of the limiting block. The upper end of the clamping block penetrates through the first opening and extends to the outside and is fixedly connected with a pulling block. One end of the first spring is fixedly connected with the pulling block, and the other end of the first spring is fixedly connected with the fixing block. A storage box is fixedly arranged on the upper end surface of the vehicle body, and an elastic limiting mechanism is arranged in the storage box. The structure of the utility model is reasonable. The rollers of the vehicle body can be replaced for different roads, so that the flatness of different roads can be measured. At the same time, the road surface flatness detector placed can be fixed to prevent it from falling and being damaged.

[0005] Although the above patent has a reasonable structure, the rollers of the vehicle body can be replaced for different roads, so that the flatness of different roads can be measured. At the same time, the road surface flatness detector placed can be fixed to prevent it from falling and being damaged, but it is not convenient to buffer the impact force and it is difficult to reduce the influence of road debris on the detection result.

[0006] Therefore, it is very necessary to invent a road surface flatness detection device to solve the above problems. Content of the Utility Model

A limit piece is fixedly connected to one end of the sliding rod. A pressure spring is fixedly connected to one side of the limit piece. The pressure spring is convenient for deforming to generate elastic force to offset part of the impact.

[0014] As a further scheme of the utility model, a support sliding rod is fixedly connected to the top surface of the support plate. A chute adapted to the support sliding rod is opened at the bottom of the vehicle body. The chute is convenient for the support sliding rod to slide.

[0018] (III) Beneficial effects

[0019] The utility model provides a road surface flatness detection device, which has the following beneficial effects:

[0020] 1. For the road surface flatness detection device, through the settings of the shock absorption component and the adjustment component, when the detection device moves, the force generated by the vibration reaches the damping hydraulic column through the vehicle body. The damping hydraulic column shrinks under the force, and the buffer spring deforms under the force to generate elastic force, so as to achieve the effect of shock absorption and reduce the vibration received by the detector. At the same time, according to the detectors of different widths, turn the knob to drive the threaded rod, and the fixed block on the side frame rotates threadedly on the surface of the threaded rod, pushing the side frame to slide on the surface of the fixed frame, so as to achieve the effect of clamping and fixing detectors of different widths, improving the service life and applicability of the road surface flatness detection device.

[0021] 2. For the road surface flatness detection device, through the settings of the buffer component and the baffle, drag the vehicle body to move through the connecting frame. When there are sundries such as stones on the road surface, the baffle can block the impact of heavy objects. The impact generated by the impact pushes the support slide rod at the top of the baffle to slide inside the vehicle body. The slide rod slides inside the support piece, and the limit piece pulls the pressure spring to deform under the force to generate elastic force, so as to achieve the effect of buffering the impact force. At the same time, the cleaning brush at the bottom scrapes the fine sundries on the road surface, reducing the influence of road sundries on the detection result and improving the safety and accuracy of the road surface flatness detection device.
